To all whom it may concern:

Be it known that I, ALPHONSE REIs, of Antwerp, in the Kingdom ofBelgium, have inventcd new and useful Improvements in Pumps, (for whichI have obtained a patent in Belgium bearing date th of September, 1883,N o. 62,509; in France bearing date 5th of September, 1883, No. 157,395, in England hearing date 10th of December, 1883, No. 5,688; in

Germany hearing date 12th of December, 1883,

No. 27 ,746, and in Austria bearing date 27th of April, 1884,No. 2,7l7,)of which the following is a specification.

In describing the invention reference will be made to the anneXeddrawings, in which Figure 1 is a longitudinal section, and Fig. 2 is aplan View, of a pump embodying my in vention.

The pump, which may be placed horizontally or vertieally, as desired,compriscs a ram-piston working in a cylinder which itself forms thepiston of a second cylinder which is fixed; or, what is the same, afixed cylinder through which passes a piston-cylinder moved to and froand in the interior of which works a rampiston. The ram-piston, beingequally moved to and fro, produces the suction and discharge of fluid,while the cylindenpiston serves as distributer only, as hereinafterdescribed.

C is the fixed cylinder formed in two parts, c and d, for convenience ofconstruction, and carrying the suction and discharge pipes H and H.

The two parts forming the cylinder C have three stuffing-boxes, as shownin the drawings, and between these stuffing boxes are situated twoannular cavities, G G', one of which serves to admit and the other todischarge the gases or liquids. These stuffingboxes prevent the cavitiesG G' from communicating between each other or with the exteror.

A is the rampiston, and B the cylinder-piston. They are set in motion bya rotating cam, D, keyed on the shaft E. This cam carries a cranlr-pin,F, and thus serves at the same time as a cam, and as a crank adapted toproduce the two different motions necessary for the pistons A and B. Thecam D operatcs the distributing-cylinder B by means of twofriction-rollers, g g', mounted ou a frame,'I, which is fixed to thecylinder and carries a slide into which fits boss D', cast in one piecewith the cam. The crank-pin F is connected directly with thecam-cylinder A by means of a connecting-rod, as shown` in the drawings.The cylinder-piston B is provided in the interior with a partitiou, P,situated at the end .of the stroke of the piston A, and is perforatedover the whole of its circumference with two series of small holes, tt', the aggregate` superficial area of which is equal to that of the suction or discharge openings H H'. The cam D has for its object to placethe apertures t t' alternately opposite the suction and dischargecavities G G'. The shape and dimensions of the cam D are so calculatedthat the crank F actuates the piston A at the proper moment-thatis tosay, when the apertures of the piston B and cylinder G are face to face.These two combined motions therefore produce the suction and dischargeof the liquids and the gases without the assistance of valves. Theprincipal causesof wear and tear and disturbance are therefore obviatedby this system, the friction surfaces being constantly kept in goodorder by the stuffing-boxcs. The degree of tightness may be controlledby the stuffing-boxes according to the pressure of the discharge to beproduced.

The combination of the motions and the shape of the cam permit theimparting to the punp of a reciprocating motion in either direction, andtherefore the reversing of the action of the suction and discharge pipesat will. For this purpose it is sufficient to reverse the pump in anysuitable way by a set of pulleys and driving-belts or in any othersuitable manner.

The packiug used for the stuffing-boxes may vary according to the natureor temperature of the liquids or gases to be pumped. The materialspreferably used for this purpose are oakum, asbestus, or cotton; but anyother packing may be employed to suit special cases, either metallic,Vegetable, or animal.

What I claim as my invention, and desire to Viees whereby both the rampiston A and secure by Letters Patent, isr the eylindrioal piston B areaetuated by the In a reversible pump, a fixed eylinder, O, I movement ofsaid cam D, as and for the purprovided with the annula' cavities G G',leadpose described.
